Resubmitting patch from Al Viro <viro@zeniv.linux.org.uk>, with subject -
[PATCH] s2io LRO bugs.
a) initiate_new_session() sets ->tcp_ack to ntohl(...); everything
else stores and expects to find there the net-endian value.
b) check for monotonic timestamps in verify_l3_l4_lro_capable()
compares the value sitting in TCP option (right there in the skb->data,
net-endian 32bit) with the value picked from earlier packet.
Doing that without ntohl() is an interesting idea and it might even
work occasionally; unfortunately, it's quite broken.

macb devices are only found integrated on SoCs, so they can't be
hotplugged. Thus, the probe() and exit() functions can be __init and
__exit, respectively. By using platform_driver_probe() instead of
platform_driver_register(), there won't be any references to the
discarded probe() function after the driver has loaded.
This also fixes a section mismatch due to macb_probe(), defined as
__devinit, calling macb_get_hwaddr, defined as __init.

Investigating each case closer it looked like all
referred functions are only used in the init phase
or during hotplug.
So to avoid wasting too much memory in the non-hotplug
case the simpler fix was to allow the fuctions to
use code/data from the __devinit sections.
This was done in all four case by adding the __ref
annotation.

This change is rather temporary and is in preparation of using generic commands

However, before this happens, we'll have to remove all typedefs and teach
idefloppy_create_mode_sense_cmd() to work directly on u8 buffers.
Also, since idefloppy_get_capability_page() was used to read only the sfrp bit,
rename the latter so that the name reflects what it does.

There were two almost identical function names in ide-floppy.c, which makes
their distinction almost impossible. While ide_floppy_release() cleans up the
object after the last reference to it has been dropped, idefloppy_release() is
the blkdev .release method from struct block_device_operations which releases
that last reference.

The CAPACITY_LEVEL stuff defines various levels of charge; however, what
is the difference between them? What differentiates between HIGH and NORMAL,
LOW and CRITICAL, etc?
As it appears that these are fairly arbitrary, we end up making such policy
decisions in the kernel (or in hardware). This is the sort of decision that
should be made in userspace, not in the kernel.
If the hardware does not support _CAPACITY and it cannot be easily calculated,
then perhaps the driver should register a custom CAPACITY_LEVEL attribute;
however, userspace should not become accustomed to looking for such a thing,
and we should certainly not encourage drivers to provide CAPACITY_LEVEL
stubs.
The following removes support for POWER_SUPPLY_PROP_CAPACITY_LEVEL. The
OLPC battery driver is the only driver making use of this, so it's
removed from there as well.

On ACPI systems the target state set by acpi_pm_set_target() is
reset by acpi_pm_finish(), but that need not be called if the
suspend fails. All platforms that use the .set_target() global
suspend callback are affected by analogous issues.
For this reason, we need an additional global suspend callback that
will reset the target state regardless of whether or not the suspend
is successful. Also, it is reasonable to rename the .set_target()
callback, since it will be used for a different purpose on ACPI
systems (due to ACPI 1.0x code ordering requirements).
Introduce the global suspend callback .end() to be executed at the
end of the suspend sequence and rename the .set_target() global
suspend callback to .begin().

PCI Express ASPM defines a protocol for PCI Express components in the D0
state to reduce Link power by placing their Links into a low power state
and instructing the other end of the Link to do likewise. This
capability allows hardware-autonomous, dynamic Link power reduction
beyond what is achievable by software-only controlled power management.
However, The device should be configured by software appropriately.
Enabling ASPM will save power, but will introduce device latency.
This patch adds ASPM support in Linux. It introduces a global policy for
ASPM, a sysfs file /sys/module/pcie_aspm/parameters/policy can control
it. The interface can be used as a boot option too. Currently we have
below setting:
-default, BIOS default setting
-powersave, highest power saving mode, enable all available ASPM
state
and clock power management
-performance, highest performance, disable ASPM and clock power
management
By default, the 'default' policy is used currently.
In my test, power difference between powersave mode and performance mode
is about 1.3w in a system with 3 PCIE links.

If the fakephp driver is used to emulate removal of a PCI device by
writing text string "0" to the "power" sysfs attribute file, this causes
its parent directory and its contents (including the "power" file) to be
deleted before the write operation returns. Unfortunately, it ends up
in a deadlock waiting for itself to complete.
The deadlock is as follows: sysfs_write_file calls flush_write_buffer
which calls sysfs_get_active_two before calling power_write_file in
pci_hotplug_core.c via the sysfs store operation. The power_write_file
function calls disable_slot in fakephp.c via the slot operation. The
disable_slot function calls remove_slot which calls pci_hp_deregister
(back in pci_hotplug_core.c) which calls fs_remove_slot which calls
sysfs_remove_file to remove the "power" file. The sysfs_remove_file
function calls sysfs_hash_and_remove which calls sysfs_addrm_finish
which calls sysfs_deactivate. The sysfs_deactivate function sees that
something has an active reference on the sysfs_dirent (from the
previous call to sysfs_get_active_two back up the call stack somewhere)
so waits for the active reference to go away, which is of course
impossible.
The problem has been present since 2.6.21.
This patch breaks the deadlock by queuing work queue items on a single-
threaded work queue to remove a slot from sysfs, and to rescan the PCI
buses. There is also some protection against disabling a slot that is
already being removed.

This patch converts users of pci_enable_device_bars() to the new
pci_enable_device_{io,mem} interface.
The new API fits nicely, except maybe for the QLA case where a bit of
code re-organization might be a good idea but I prefer sticking to the
simple patch as I don't have hardware to test on.
I'll also need some feedback on the cs5520 change.

The pci_enable_device_bars() interface isn't well suited to PCI
because you can't actually enable/disable BARs individually on
a device. So for example, if a device has 2 memory BARs 0 and 1,
and one of them (let's say 1) has not been successfully allocated
by the firmware or the kernel, then enabling memory decoding
shouldn't be permitted for the entire device since it will decode
whatever random address is still in that BAR 1.
So a device must be either fully enabled for IO, for Memory, or
for both. Not on a per-BAR basis.
This provides two new functions, pci_enable_device_io() and
pci_enable_device_mem() to replace pci_enable_device_bars(). The
implementation internally builds a BAR mask in order to be able
to use existing arch infrastructure.

Convert quirk printks to dev_printk().
I made the MSI disable messages a little more consistent:
- always use "disabled", not "deactivated"
- specify "device MSI disabled" or "subordinate MSI disabled" when
disabling MSI for only a specific device or subordinate bus

Instead of printing this:
PCI: Calling quirk c023b250 for 0000:00:00.0
we can print this:
pci 0000:00:00.0: calling quirk 0xc023b270: quirk_cardbus_legacy+0x0/0x30()
The address is superfluous because sprint_symbol() includes the
address if the symbol lookup fails, but this is the same style used
in do_initcalls() and pnp_fixup_device().

The current pci_assign_unassigned_resources() code doesn't work properly
on 32 bits platforms with 64 bits resources. The main reason is the use
of unsigned long in various places instead of resource_size_t.
This is a pre-requisite for making powerpc use the generic code instead of
its own half-useful implementation.

Earlier patches to split out the hardware init for PCIe hotplug resulted in
some one-time initializations being redone on every resume cycle. Eg.
irq/polling initialization.
This patch splits the hardware init into two parts, and separates the
one-time initializations from those so that they only ever get done once,
as intended.

PCI error recovery usually involves the PCI adapter being reset.
If the device is using MSI, the reset will cause the MSI state
to be lost; the device driver needs to restore the MSI state.
The pci_restore_msi_state() routine is currently protected
by CONFIG_PM; remove this, and also export the symbol, so
that it can be used in a modle.
